It sounds like you have an interesting assignment that will provide many opportunities to learn and make a difference. My understanding of your question is that you have asked to develop a planning session with a community and that this is expected to result in a project that will be done with the community.
Here are a few questions to consider as you go about envisioning what might be done in this assignment: (1) What community are you hoping to work with and has this community worked with your campus/organization, etc? (In other words, are there already some relationships you can build on to get started?); (2) What resources could you, your campus, and your partner bring to the project?; (3) What kind of time frame do you have in mind (this ends up being very important because you want to "size" the project and planning in ways that fit with the time available?; (4) What kinds of outcomes might you, your campus, and your partner be interested in achieving?
You will find many useful resources in the Community Tool Box that will help you think about these questions: Chapt 1: Our Model for Community Change, Chapt 3: Assessing Community Needs and Resources, Chapt 5: Choosing Strategies to Promote Community Health and Development, Chapt 8: Developing a Strategic Plan, Chapt 17: Analyzing Community Problems and Solutions; Chapt 18: Deciding Where to Start, Chapt 19: Choosing and Adapting Community Interventions.
Each of these chapters is filled with resources and ideas that you might find useful.
